ORE CONCEN TRATIN G AN D SEPARATING APPARATUS.

l Specication of Letters Patent. Application led April 15, 1908.

Patented Apr. 5, 1910. serial No. 427,147.

To all whom `t may concern:

lie it known that I, FRANois DALLE- MAGNE, citizen of France, residing at Irun, in the Kingdom of Spain, have invented new and useful Improvements in Ore Concentrating and bepa-rating Apparatus, of which the following is a specification. f

This invention relates to an apparatus for separating by very simple mechanicil means, complex ores finely mixed and having a difference of density of only the two thousandths part of the unit. In suchy system of separation, the differences of density and equivalence of ores are brought into use and it has been endeavored to obtain the'sorting by employing the first moment of the fall of the particles to be separated.

To this end, a grooved platform is used, to which is imparted, through a special device, an alternating oscillatory circular movement which can impart to the materials to be sorted a number of oscillations reaching to 2,000 per minute. A grain of the material may thus receive up to 100,000 oscillations before leaving the platform. This power of sorting is precise y that which allows of the separation of very fine materials, whose densities approach very much one to the other.

` The device allows of modifying the form of the circular movement and thus to utilize either the horizontal movement or the vertical movement or any combination of the two.

In the accompanying drawings: Figure l is a front view of the apparatus; Fig. 2 is a plan view; Fig. 3 is a cross sectional View; Fig. 4 is a lon itudinal section through the recuperator; ig. 5 is a detail front view on a large scale of certain parts for the transmission of motion; Fig. 6 is an end view of the arts shown in Fi 5; Fig. 7 is' an enlarged section of one o the grooves in the platform of the apparatus;

ig. 8 is a view on a large scale of the device allowing of regulating the inclination of the platform.

The base of the apparatus is formed by an appropriately strutted rigid metallic frame z. he'drivlng shaft b and its fly-wheel b lctuated by pulleys w w impart the alternaive motion to the sector a', and to theshaft r through the connecting rod c. The flyvheel Za is provided with a slot b2 in which he pin b3 of connecting rod c is adjustable. The simple displacement of the pin g on the actor d allows of varying the form Vof the one toanother through eral distinct channels o o o2 motion as will be seen hereinafter.` The shaft e, through the medium of the crank /z and the connecting rod f, communicates its motion to other cranks and to other parallel shafts e on which are keyed the cranks L. On said cranks 7e., are pivoted levers L to which is secured a rigid frame z' which follows the alternative circular motion. On framez' rests another movable frame k, which may be suitably inclined, by means of a screw n. This screw acts on a lever/w, keyed on a longitudinal shaft n', mounted on supports secured to the frame On said shaftn are keyed at convenient distances, five small crank-arms fw the pins of which are engaged in eyes formed in the supports secured to the fra-me la. It will be understood that by either rotating the shafth'n/ in one direction or in the opposite direction, the small crank arms w will cause the platform m to ascend or descend. The rotation of said shaft n is insured by the screw n which, when unscrewed inits support, draws down the lever w and, when screwed, allows such lever to rise by reason of the weight exerted by the platform on such lever. This operation may be easily understood by reference to Fig. '8.

The frames i and la are movably secured an axle j which conthe five angle-iron cross-pieces which acts as struts for said frame. O n the frame c is a latform m, of any rigid material and o? rectangular, trapezoidal or any other shape. Such platform m is provided with longitudinal parallel grooves fr, whose section is shown in Fig. 7. The depth of such grooves dimin-y ishes as it ap roaches the curve p s which ends them. perforated pipe g supiplies the platform m with the water require .for working. The separated materials fall lnto a recuperator o which is composed of sevo3 whichV severa ly receive a single material. Their bottoms are inclined so that the materials beY discharged through the orifices 0. The 1 nner channel u is movable and may be sltuated at the desired point p certain class` of materials. The materlals enter through a distributer y and are conducted from the llatform m to the channels i) the recuperator by means of rigid plates t which may be placed at the desired points an be of slze necessary for the work. r

nects 1n pairs each of 25 f imparted to the The function of grooves r, whosesection is indicated in Fig. 7, is to be filled with materials of greater density, which through the oscillatory motion imparted by the apparatus, sort themselves as in a screen, an as the materials advance lengthwise, the rooves being shallower, the upper part of' t ematerials, that is to say the lighter materials, 'rise above the level of the platform and are carried into the next oove, which is parallel, and which will effect the same operation .until the materials of same density, meet 1n the same groove or grooves, whichv they then follow to the end, and fall at a sameplace of the discharge channels 0 o o2 03.

The motion of the platform lml may be `varied according to the nature of the ores to be sorted, by moving tlie pin g on the sector d. It will be understood that by such movement, the operative angle of the crank shafts h and accordingly the form of the motion of levers h', of frame i and of platform m will be modified. By this means a vertical oscillatory motion, or a horizontal oscillatory motion, or a combination of both, may be latform m. In addition to this the amplltude of all said motions may be varied by displacing the pin b8 of the connecting rod cin slot b2 of the iy-wheel b Having now described my invention, w at I claim as new and desire to secure by ters Patent is:

1. In an ore concentrating and separating apparatus, the combination of a stationary frame, a movable frame arranged above said stationary frame, a platform secured to said movable fra-me, cross shafts parallel one with each other journaled in the stationary frame, means for imparting to the first cross shaft an alternating rotary motion, cranks keyed on the cross shafts, a rod connecting said cranks, and levers pivoted on said cranks and fixed to the movable frame, substantially as described and for the purpose set forth.

2. In an ore concentrating and separating apparatus, the combination of a stationary frame,a movable framearranged above said stationary frame, a platform connected to said movable frame, means for inclinilig said platform with relation to the movable frame, cross shafts parallel one with each other journaled in the stationary frame, a sector fixed on the first cross shaft, a pin adjustably secured on said sector, a driving shaft j'ournaled on the stationary frame, a crank fly wheel fixed on said driving shaft, a rod connecting the pin to an adjustable point of the crank fly wheel, cranks keyed on the cross shafts, a rod connecting said cranks, and levers pivoted on said cranks and fixed to the movable frame, substantially as described and for the purpose set forth.

3. In an ore concentrating and separating apparatus, the combination of a stationary frame, a movable frame arranged above said stationary frame, a platform' connected to said movable frame, a screw mounted on said movable frame, a longitudinal shaft journaled on said movable frame, a lever keyed on said longitudinal shaft and engagin the screw, small crank arms keyed on said lon itudinal shaft, supports secured to the p lat orm and provided with elongated eyes in Awhich are engaged the pins of the small crank arms, cross shafts parallel one .with each other journaled in the stationary Letl frame, a sector fixed to the first cross shaft, a 'pin adjustably secured on said sector, a driving shaft journaled on the stationary frame, a crank fly wheel xed on said driving shaft, a rod connecting the pin to an adjustable point of the crank fly wheel, cranks keyed on the cross shafts, a rod connecting said cranks, and levers pivoted on said cranks and fixed to the movable frame, substantially as described and for the purpose set forth.
